If you've ever felt drained after doing a crossword puzzle, working a math problem or taking a test, there's a reason, says Dr. Paul Foster, professor of clinical psychology at Middle Tennessee State University and a practicing psychologist at Murfreesboro Medical Clinic.

"There is an idea out there that you have a process of cognitive fatigue that is similar to physical fatigue. If you're exercising, you get tired. If you're using your brain, it feels tired," Foster says.
